[android-developers] registerForContextMenu not working
Hi everyone, My context menus are not registering when called. In
addition setOnItemClickListener is also not working. Any ideas why
this is happening?
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.armory_header);
TabHost mTabHost = getTabHost();
mTabHost.addTab(mTabHost.newTabSpec("1").setIndicator("Weapons").setContent(R.id.page1));
mTabHost.addTab(mTabHost.newTabSpec("2").setIndicator("Armor").setContent(R.id.page2));
mTabHost.addTab(mTabHost.newTabSpec("3").setIndicator("Accessories").setContent(R.id.page3));
weapons = (ListView) findViewById(R.id.weaponlist);
registerForContextMenu(weapons);
weapons.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView arg0,
View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
listId = weapons.getId();
position = arg2;
showDialog(DIALOG);
}
});
armor = (ListView) findViewById(R.id.armorlist);
registerForContextMenu(armor);
armor.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView arg0,
View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
listId = armor.getId();
position = arg2;
showDialog(DIALOG);
}
});
}

[android-developers] ListView contextmenu and onItemClickListener not working
I have a tab activity with three tabs and I want to display a listview
in each tab. The list populates correctly, but for some reason I can
not get the context menu or itemclicklistener to recognize gestures on
the listviews. Anyone have any ideas why this might be? Below is my
onCreate method:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.armory_header);
TabHost mTabHost = getTabHost();
mTabHost.addTab(mTabHost.newTabSpec("1").setIndicator("Weapons").setContent(R.id.page1));
mTabHost.addTab(mTabHost.newTabSpec("2").setIndicator("Armor").setContent(R.id.page2));
mTabHost.addTab(mTabHost.newTabSpec("3").setIndicator("Accessories").setContent(R.id.page3));
weapons = (ListView) findViewById(R.id.weaponlist);
registerForContextMenu(weapons);
weapons.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView arg0,
View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
listId = weapons.getId();
position = arg2;
showDialog(DIALOG);
}
});
armor = (ListView) findViewById(R.id.armorlist);
registerForContextMenu(armor);
armor.setOnItemClickListener(new OnItemClickListener(){
@Override
public void onItemClick(AdapterView arg0,
View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
listId = armor.getId();
position = arg2;
showDialog(DIALOG);
}
});
}

[android-developers] Re: Null pointer exception
That was it! I took out the startManagingCursor() and it worked
fine. My next question is what should I do to handle the life cycle
of my cursor? Should I close it outside the switch statement?

[android-developers] Re: Null pointer exception
Ok, I tried gino's idea with initializing my arrays differently. I
also changed there names so that they did not share a name with any
other arrays in my app: Did not work.
I also tried calling to static variables instead of passing variables
between classes with intents: This also did not work.
I can't determine which line of code causes the error. The logcat
does not give me a pointer to anything in my app at all. I tried to
narrow it down with breakpoints and logging and what I found is that
it runs through all of my code without a hitch, and then once its done
it throws the exception.
And again the exception only happens when I call the intent from a
contextMenu.

[android-developers] Re: Null pointer exception
This is bizarre.
It works fine from the OnItemClick() of my OnItemClickListener
attached to my ListView. Just not inside the onContextItemSelected.

[android-developers] Re: Null pointer exception
yes, Select.class is another one of my files. throughout my app there
are a few different calls to it, all done the same way i.e. "Intent i
= new Intent(this, Select.class); startActivity(i);"
No where in Select.class do I make a call to start Select.class or
Sheet.class. When its done it calls finish();
in the onCreate() of Select.class I grab the extras from the invoking
class with this line of code:
public class Select extends ListActivity{
DBAdapter db = new DBAdapter(this);
String slotName = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
db.open();
ListView list = getListView();
View v = View.inflate(this, R.layout.list_header, null);
list.addHeaderView(v, null, false);
name = this.getIntent().getStringExtra(DBAdapter.KEY_NAME);
}
Could it be something in the .getIntent() method? or
the .getStringExtra()?

[android-developers] Re: Null pointer exception
Ok, I'm suddenly very curious by your previous statement stephen about
the possibility of creating an infinite loop. Upon a little more
investigation I'm now getting errors all over the place...same
errorjust at different points in the app where I try to
startActivity(intent); As soon as the new activity receives focus is
crashes.

Hmm, Ok, I've placed the breakpoint in and everything appears to be
fine, but it still doesn't work. This code is essentially a copy/
paste from another area of my app. In that instance its being called
from a ListView contextmenu as well and works fine. What do you mean
exactly by catching ALL the exceptions? Is that something I need to
add into the code?

Yes I'm using eclipse. I use the debugger and when I hit that point
in my app i get the above error in my logcat window. Is there another
way to debug in eclipse?

This is the code it runs when I get the error (this is a context menu
option from a listview)
Cursor c = db.getInfo(name);
c.moveToPosition(info.position - 1);
Intent i = new Intent(this, Select.class);
i.putExtra(name, c.getString(c.getColumnIndexOrThrow
(DBAdapter.KEY_NAME)));
startActivity(i);
this launches another activity that when opened from other areas of my
app work fine. I checked to see if it had anything to do with the
extras and it didn't seem to(i removed them entirely).

[android-developers] ListActivity and headers giving me an odd side effect
Hello, I'm getting some odd side effects when I set a header to my ListActivities. The ListActivity actually allows you to scroll up "behind" the header and click...which sends my app into a fit of errors b/c my Lists are connected to a Cursor and selecting behind the header returns a value of -1. Ive noticed this doesnt happen to any of my Lists that dont have headers. Any ideas what would cause this/ how to fix it?

[android-developers] Dynamic Spinners
Hello,
I'm attempting to create and display Spinner view and an EditText view
when the user hits a button. I can create these with .addView, and
assign Ids with .setId() but then how would I call .getSelectedItem
() or .getText() on them?
Heres some of my code:
attrLayout = (LinearLayout) findViewById(R.id.attrlayout);
addAttr = (Button) findViewById(R.id.addattr);
addAttr.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Spinner newAttrSpinner = new
Spinner(arg0.getContext());
newAttrSpinner.setId(spinId);
newAttrSpinner.setAdapter(attrAdapter);
EditText newEditText = new
EditText(arg0.getContext());
newEditText.setId(editTextId);
newEditText.setWidth(100);
attrLayout.addView(newAttrSpinner);
attrLayout.addView(newEditText);
}
});

[android-developers] Re: Accessing images from gallery
Well the console view in eclipse spits this out when I start the
emulator:
ActivityManager: DDM dispatch reg wait timeout
ActivityManager: Can't dispatch DDM chunk 52454151: no handler defined
but other than that it runs fine. The errors start occurring on my
actual phone when I test it there. I knew about using the logcat to
view errors in the emulator, is there a way to do that when I'm
testing on the phone? Its an HTC G1 btw.

[android-developers] Accessing images from gallery
Hi,
I'm a mess.
I'm using the blow code to open the gallery and grab an image for an
incon im gong to store in a database and access later to populate a
listview attached to a simpleCursorAdapter.
//inside contextmenu
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(intent, 1);
//activityresult
protected void onActivityResult(int requestCode, int resultCode,Intent
data)
{
if(requestCode == 1){
if(resultCode == RESULT_OK) {
db.open();
db.updateDB(data.getData().toString()); //this updates
the columns in the DB that will later get used for the adapter
db.close();
}
}
}
The code runs, and then starts force closing (what seems like)
randomly. I'm convinced that I've gotten something confused somewhere
but since the force closure happens at all different points of my app
I dont know where to start looking.

[android-developers] Re: binding images from assets to a simpleCursorAdapter
Well then I am probably doing this the wrong way.

[android-developers] binding images from assets to a simpleCursorAdapter
Hello, I was poking around in the documentation for the simpleCursorAdapter and I read that if the simpleCursorAdapter doesn't identify your images as resources it will assume they are URIs. My question is how do i retrieve the URI for an image placed into the asset folder of my application? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Re: MediaStore returning loop of images and not entire directory
I implemented a bit of code at the end there before you recycle the
bitmap to open a fileoutput stream and write the image to the /data/
data//file directory and save it there after the scaling.
What I need to figure out is how to grab that images URI so that I can
bind it to a simpleCursorAdapter. Does the image even have a URI
after I place it into the apps file dir? or should I instead of
copying it to the file dir just reference the original image on the
sdcard?

[android-developers] MediaStore returning loop of images and not entire directory
Hello, I'm testing some code from a demo found in a forum and I'm
getting some strange results. My goal is to be able to allow users to
access the pictures on their device to choose an avatar/logo. This
code run flawlessly except that I only get a handful of images on the
phone. And its not even always the same images. Whats more is that
it loads those images into a gridview and repeats them for what looks
like a number of times equal to the actual number of images that are
on the device. And on top of that if I scroll down the through the
pictures, and scroll back up, it reorders the pictures from what they
were previously. Each time I load the app the pictures seem to be
different as well. I have around 400 pictures stored on my phone, and
thats what I'm using to test. If someone could shed some light on
this for me that would be great. This is my first time using a URI to
access content to I'm not sure where to start troubleshooting this
one.

Heres another concern. I previously had 2 separate contextmenus and 2 separate options menus for my first tab and my second tab. Now that they are in the same activity do they have to share the same menus?

[android-developers] Re: RESET SQLite AUTOINCREMENT
I'm very new to all of this so I greatly appreciate your advice. But
to clarify, you mean instead of using AUTOINCREMENT i create a column
to hold an integer value that I set, and can therefore control rather
than let SQLite do it automatically? This was what I was expecting to
have to do if there wasn't a work around. I had read that deleting
the table row from the sqlite_sequence table would reset it, however,
this didn't seem to work for me.

[android-developers] Re: RESET SQLite AUTOINCREMENT
I use a do/while that runs through one of my tables based on the
number of entries on another table and makes changes.
Example:
Integer i = 1;
Cursor c = db.querryFunction();
Integer rowCount = c.getCount();
do{
//does work on the database
db.updateRow(table, args, KEY_ROWID + "=" + i, null);
i++;
}
while(i <= rowCount);
if my autoincrements skips numbers then I can get an error trying to
update a row that doesn't exist.

Hello, I have a database that will be editable inside my android app. I'm having an issue where when a row is deleted, its spot in the autoincrement array is still taken, and subsequent entries into that table pick up after that number. This leaves me with a list of rows whos autoincrement id values can jump around. I need my rows in my database to stay ascending and in increments of 1. Is there an easy way to do this? Or will I need to rewrite the autoincrement column to all my rows each time an item is deleted? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] Need help with using multiple views within a Listview
Hi all, I,m trying to build a custom Listview and Adapter to populate the screen with items from a database. I need to have a checkbox in each view that when clicked will display a number in a textview from the database within that particular Listview item, and then also update the checked status in the database. Anyone have an example of how I could make this work? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.

[android-developers] no reply from android beginners....can anyone help?
Im trying to fill a spinner with data from a table. That part works
fine. What i cant figure out is how to use the selection made
through
the spinner. if i use :
String someString = (String) classSpin.getSelectedItem().toString();
i get some sort of SQL reference. Am i missing a step? Im new to
both java and android so i hope this is something very obvious im
missing.
heres some of my code for the spinner:
Cursor classCur = db.getClasses();
startManagingCursor(classCur);
from = new String[]{DBAdapterStats2.KEY_CLASS};
to = new int[]{android.R.id.text1};
SimpleCursorAdapter classAdapter = new SimpleCursorAdapter(this,
android.R.layout.simple_spinner_item, classCur, from, to);
classAdapter.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
classSpin.setAdapter(classAdapter);

[android-developers] R.java not compiling properly? need help :(
Im having an issue with Eclipse where it will suddenly not be able to
read my R.java file and all of my resource references get errors. Ive
tried doing a fresh install of Eclipse and that did not help.
Rebuilding apps does not help. Fixing project properties does not
help. Here's an example of one of my errors within my R.java {Illegal
modifier for the class id; only public, abstract & final are
permitted}...there arent any modifiers other than what is permitted b/
c its automatically generated and i cant edit it. What in the world
have I done? And is there a way to fix it?
